The DV mouthpiece is an excellent mouthpiece for anyone coming from tenor, and suits a wide range of styes of playing with its punchy, overtone-rich sound. For best intonation, be careful to find the 'sweet spot' on the crook, which might be a little further onto the cork than expected. I used a tuner to find the best place for all registers (the rest is down to the player!). Once you have it right, playability is fantastic.
